Self-consumption Systems

Priority to renewable energy without grid-injection
When it is forbidden or there is no incentive to inject energy into the public grid, an Xtender inverter/charger combined with VarioTrack or VarioString MPPT solar charge controller will minimize the grid consumption in favour of the locally...

Optimising self-consumption
In this context, the storage system is connected at the end of the grid electricity line. The sizes of the PV installation and the loads are not important. The SCADA system can control the Xtender as a function of the available solar energy (extra...

Optimising self-consumption with battery backup
This system has the advantage of being easily integrated into an existing grid-feeding installation even when its power is higher than that of the Xtender. The self-consumption is optimized by means of an expert control system (SCADA) supplied by...

Optimising self-consumption with battery and solar backup
This system will secure all user (household) appliances however it requires that the power of the Xtender is at least equivalent to the grid inverter and that it covers the household’s power needs. The self-consumption is optimized by means of an...

Simple solar priority system
Compact series inverter/charger with built-in (or external) solar charger allows to buildup a simple solar backup system with solar priority. The connected loads run on the sun as long as there is enough energy in the system. When the battery is...
